MultipleSubdomains
Example
If your landing page is mysite.com and your confirmation page is checkout.mysite.com, you should enable Rokt’s referral tag to store the Rokt Click ID as a first-party cookie that can be accessed across subdomains.
Add the folowing code to the <head> on your landing page:
<script src="https://apps.rokt.com/integrations/referral-tag/referral-tag.js" data-fp-domain="your_base_domain" async></script>”
